This is even more cool than the micro RC cars that came out a few years ago
(not much bigger than 'matchbox/hotwheel' cars).
The double propellers is actually not that new, but genius nonetheless.
Before Igor Sikorsky created the first 'practical' helicopter (contrary to
popular belief he did not INVENT the helicopter), there were many different
ideas tried to keep the machine from rotating and the double blade was one
of them. It worked, but was very complicated mechanically (There are
actually a few full size helicopters that work this way even now). Sikorsky
realized that the rear stabilizer propeller (the 'tail blade') was not the
perfect solution, but it was the best solution from a practical standpoint.
It's ironic that the more complex counter-rotation problem is finally solved
in a toy.
